Chapter 3 Section 4 Slope-Intercept Form
Slope and y-intercept • Recall the slope of a line is the rate at which it either climbs or descends. It is the ratio of the change-in-y over the change-in-x. • The y-intercept is the point where the graph crosses the y-axis. The x value is 0 here.
Draw a line that has slope of 2 and passes through the point (0, 3).
